Removing Red Eye

The following example was using "Photoshop Elements" but can be duplicated in Photoshop or another photo editing program.
Step 1. Zoom in on the red eye until you can clearly see the boundary between the pupil and the iris.
Step 2. Select the "Elliptical Marquee" tool and draw a circle over the red or orange portion of the eye as shown in Figure 1 below. Use the arrow keys on your keyboard to nudge the circle until it's in the proper position.
Step 3. Open the "Select" menu and choose "Feather", and type in 5 for the number of pixels as in the photo below. This option blurs the edge of the selection so the effect won't produce a hard edge.
Step 4. From the main menu go to "Enhance Color" and choose "Hue/Saturation". In this dialogue box decrease the saturation to its lowest possible level (such as the negative -100 setting shown in the photo below and lower the lightness setting slightly.
This process will eliminate the red and restore the appearance of a dark pupil, yet the eye will retain the glint of a natural look.
